...M16 bolt carriers are not designed and intended solely and exclusively for use in converting a weapon into a machinegun and are not any combination of parts from which a machinegun can be assembled. Further, an M16 bolt carrier is not a firearm as defined in the GCA or a machinegun as defined in the NFA. An M16 bolt carrier is simply a machinegun part and as such its domestic sale and possession is unregulated under the Federal firearms laws. It is not unlawful to utilize a M16 machinegun bolt carrier in a semiautomatic AR15 type rifle.

    The only choice for a BCG

    This BCG is awesome. Being a machinist, I always appreciate beautiful work, spent nearly an hour just looking at this thing when I got it. It came with the cam pin nicely lubed and the staking job is nothing short of excellent. I was interested in this particular BCG because, being the auto version, it doesn't have extra material milled away. Way better than my bushmaster and I look forward to seeing how my rifle performs with the extra mass and extractor boost in this BCG

    BCM bolt carrier group

    This is my second BCG. My first BCG group is in another AR build with several thousand rounds through it. I have not had any problems.

    Bravo Company Bolt Carrier Group

    BCG group came packed excellently. Fast shipping. BCG preformed flawlessly. The BCM BCG is replacing a BCG group I bought new and the staking on the gas key came lose in under a hundred rounds. I have no doubt in this BCG from Bravo company because it has already surpassed that mark. Buy with confidence

    BCM Bolt Carrier Group (MPI) - Auto

    I currently have 5 complete BCM uppers an have been very happy with them. So when it was time for my next build I felt it was best to get good quality parts so I ordered the BCM Carrier Group.

    Seems top notch

    I haven't had a chance to run it yet because I still have a ways to go on my build but the shipping was fast, the packaging was above adequate, and the BCG seems solid. I dig it.

    Best BCG period.

    I won't build a rifle without a BCM BCG.
